Sources for 1N3307 zener

Anybody know a good, cheaper source for the 1N3307 zener diode.
that is one expensive diode.

What is it being used in? Can you replace it with something else, like a transistor and a smaller zener? Or possibly a regulator of some type?

 

Maybe I am missing something. But, $10 from most national sources (Allied, Newark, etc.,) for a needed part like a 50 watt stud mount zener doesn't sound out of range or outrageous.

 

Your Allied link shows 0 available. Minimum order of 25, looks like.

 

Talon has a 25w version for under $6

Thanks everyone. I did a real pitiful job on this post/question. I could have supplied more info.
This zener is the bias zener for the Dentron 160-10.

Not a big help if he needs a 50 Watt Zener...

Has the OP looked at Mouser? They may have an equivalent with a different part number. I suspect any 8.2 Volt, 50 Watt Zener would work; there is also a 60 Watt, 8.2 Volt version.

 

NTE is really great for new old parts. Check out http://www.nteinc.com for NTE5249A and others, their part number for 1N3307.

 

Quite right.

But a string of regular rectifier diodes wired in reverse polarity so they use the Vf of the diodes to create a Zener effect works very well, is adjustable (add or remove rectifiers to add or subtract from the cathode bias by about 0.7V per diode), and very cheap. To hit 8.2V only takes about 10 rectifiers in series that cost $0.12/each and if rated for 3A per diode, will handle this just perfectly.

If idling current is too high, add a diode; if it's too low, subtract a diode.
